Delhi AQI:

With the Diwali season every year for the past few years, the Air Quality of the national capital Delhi deteriorates severely. And this year too, in spite of a full crackers ban, Delhi observed bursting of crackers on the occasion of Diwali, which led Delhi’s Air Quality to deteriorate. 

It must be noted that a day after Diwali, i.e., on 5th November 2021, the Delhi AQI hit “severe level” making Delhi’s air “Hazardous.” With the increasing level of pollution, the visibility dropped significantly as a thick layer of smog appeared as a blanket in the sky.

Delhi AQI at 10 AM on 5th November 2021 in Anand Vihar was recorded at 902. Moreover, the lung-damaging fine particles known as PM2.5 went up to 494 micrograms per cubic meter, and PM10 levels went up to 902 micrograms per cubic meter.

It must be noted that as per the Delhi Government’s Graded Response Action Plan (GRAP), the air quality of Delhi has entered into the emergency category ever since the PM2.5 and PM10 surged beyond 300 micrograms per cubic meter and 500 micrograms per cubic meter respectively, for more than 48 hours.
